3 Lessons
LESSONS

Lesson 1 - Types and Methods of Surface Preparation

TYPES AND METHODS OF SURFACE PREPARATION SURFACE PREPARATION REQUIREMENTS SURFACE PREPARATION

Objective

To have a basic understanding of the different types and methods of surface preparation that are available.

The methods of surface preparation include:

  • Abrasive Blast Cleaning.
  • High-Pressure Water Washing (waterjetting)
  • Mechanical Preparation.

The unit also reviews the dry ice blast cleaning process.

Lesson 2 - Types of Substrates and Materials

TYPES OF SUBSTRATES AND MATERIALS SURFACE PREPARATION REQUIREMENTS SURFACE PREPARATION

Objective

To have a basic understanding of the numerous types of substrates and materials that the protective coatings applicator may encounter, these include:

  • Steel.
  • Stainless Steel.
  • Concrete.
  • Aluminium.
  • Zinc.
  • Copper.
  • Plastic.
  • Wood.
  • Cast Iron.
  • Wrought Iron

All the above materials may be classified as substrates for paint coatings.

Lesson 3 - Pre-Surface Condition

PRE-SURFACE CONDITION SURFACE PREPARATION STANDARDS SURFACE PREPARATION

Objective

To understand the importance of pre-surface condition requirements on steel surfaces and the implications on coating performance.

  • Coating performance is dependent upon the level of preparation.
  • Abrasive blast cleaning will not remove defects in steel.
  • Pre-surface preparation is a requirement in most paint specifications.
